EV Charging Infrastructure Sizing Calculator

Level 2 chargers (7.68 kW) are ideal for workplace and residential parking where vehicles stay 4-8 hours. DC fast chargers are better for retail locations with shorter stays. Consider your typical parking duration and user needs.

Key factors include total vehicle count, EV adoption percentage, average daily driving distance, parking duration, and peak usage patterns. Future growth projections are also important for long-term planning.

Plan for future growth to avoid costly infrastructure upgrades. Most experts recommend sizing for 5-year EV adoption projections, as installations can be expensive to expand later.

Peak usage factor represents the percentage of chargers in use during the busiest times. Setting this at 80% means you're planning for high utilization while maintaining some availability for unexpected demand.

Electrical capacity depends on the number and type of chargers. Level 2 chargers typically need 7.68 kW each, while DC fast chargers require 50-150 kW. Factor in electrical panel upgrades and utility service capacity.

Yes, but plan your electrical infrastructure for full buildout from the beginning. Installing extra electrical capacity upfront is much cheaper than upgrading panels and service later.

For workplace charging, a ratio of 4-6 vehicles per charger is typical. For residential applications, aim for 2-4 vehicles per charger. Retail locations may need 1-2 vehicles per charger due to higher turnover.

Faster charging reduces the time vehicles occupy chargers, allowing more vehicles to use each station. DC fast charging can serve 3-5x more vehicles per day than Level 2 charging, but requires higher electrical capacity.
